Graphics card device

Abstract

A graphics card device includes a memory module, a graphic processing unit (GPU), a controller, a detection circuit, and a port. The GPU is electronically connected to the memory module and receives graphic data. The detection circuit determines a proportion of the graphics data occupying the memory module, and sends the proportion of the graphics that are occupying the memory module to the controller. The controller divides the memory module into a first storage space and a second storage space according to the determination. The first storage space stores graphic data received by the GPU, and the second storage space stores external data transmitted by the port.

What is claimed is:
